Corticosteroids for Guillain-Barré syndrome (Cochrane Review)

A substantive amendment to this systematic review was last made on 03 February 2000. Cochrane reviews are regularly checked and updated if necessary.

Background: The cause of Guillain-Barré syndrome (GBS) is inflammation of the peripheral nerves which corticosteroids would be expected to benefit.

Objectives: To examine the efficacy of corticosteroids in hastening recovery and reducing the long term morbidity from Guillain-Barré syndrome (GBS).

Search strategy: Search of the Cochrane Neuromuscular Disease Group register for randomised trials and enquiry from authors of trials and other experts in the field.

Selection criteria: Types of studies: quasi-randomised or randomised controlled trialsTypes of participants: patients with GBS of all ages and all degrees of severityTypes of interventions: any form of corticosteroid or adrenocorticotrophic hormoneTypes of outcome measures: Primary: improvement in disability grade on a commonly used seven point scale four weeks after randomisationSecondary: time from randomisation until recovery of unaided walking, time from randomisation until discontinuation of ventilation (for those ventilated), mortality, proportion of patients dead or disabled (unable to walk without aid) after 12 months, improvement in disability grade after six months, improvement in disability grade after 12 months, proportion of patients who relapse, and proportion of patients with adverse events related to corticosteroid treatment

Data collection and analysis: We identified six randomised trials. One author extracted the data and the other checked them. We obtained some missing data from investigators.

Main results: The six eligible trials included a total of 195 corticosteroid treated patients and 187 control subjects. One trial of intravenous methylprednisolone accounted for 243 of the total 382 subjects studied (63%). This trial did not show a significant difference in any disability related outcome between the corticosteroid and placebo groups.There was no significant difference between the corticosteroid and control groups for the primary outcome measure, improvement in disability grade four weeks after randomisation.The weighted mean difference of the three trials for which this outcome was available showed no significant difference. The actual figure was 0.01 (95% CI -0.27 to 0.29) grade in favour of the corticosteroid group.There was also no significant difference between the groups for most of the secondary outcome measures. However in the largest trial hypertension developed less often in the intravenous methylprednisolone group (2/124, 1.6%) than in the control group (12/118, 10.2%), a significant difference in favour of corticosteroid treatment (relative risk 0.20, 95% CI 0.04 to 0.66).

Reviewers' conclusions: Corticosteroids should not be used in the treatment of Guillain-Barré syndrome. If a patient with Guillain-Barré syndrome needs corticosteroid treatment for some other reason its use will probably not do harm. The effect of intravenous methylprednisolone combined with intravenous immunoglobulin in Guillain-Barré syndrome is being tested with a randomised trial.
